Abstract

Properly shielded: The fluorene groups used as capping agents for new diphenylanthracene (DPA), pyrene, and anthracene derivatives impart steric hindrance which prevents interchromophore interactions, giving these molecules high photoluminescence quantum yields. Fluorene-based DPA (1) is characterized by a highly efficient and stable blue electrogenerated chemiluminescence (ECL).
